YOC Marine Hydraulic Coupling Transmission Box

The YOC marine hydraulic coupling transmission box offers the advantages of on-load starting, overload protection, torsional vibration isolation, impact mitigation, stepless speed regulation, quick and steady clutch, and others. It is a perfect substitute for the traditional mechanical reduction gearbox of engineering ships, improving transmission performance and eliminating the problems existent in the traditional transmission devices. Therefore, the power transmission device is an ideal choice for the power unit of engineering ships.

In view of the special working conditions of such engineering ships as dredgers, sand pumping vessels, etc., our company has designed and manufactured a line of marine hydraulic coupling transmission boxes with transmitted power ranging from 100kW~8000 kW. The products provide superior performance, high reliability, and easy operation and maintenance.

Hydraulic Coupling Gravel Pump Assembly

The speed-adjustable hydraulic coupling gravel pump assembly is a brand new product designed based on the characteristics of the working conditions of dredgers, sand pumping vessels and gravel pumps. The hydraulic transmission device offers optimized construction in terms of the hydraulic coupling transmission box structure and shafting.

The hydraulic transmission product comes with integrated pump and transmission box. The head of the gravel pump, by means of the connector panel, is connected to the transmission box, and the rotor (impeller) is directly fitted onto the output shaft of the transmission box. Comparing to an original gravel pump, there are no brackets or bearing housing in the integrated structure. This hydraulic coupling gravel pump assembly has advantages of low manufacturing cost, compact structure, small size, and flexible, smooth drive.

We provide a complete line of market-oriented products which can meet any need of medium and small sized dredgers and sand pumping vessels ranging from 300 to 2000KW.
